LUBRICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 674,008, dated May 14, 1901.

Application filed February 27,1901. Serial No. 49,050. (No model.)

T 0 rtZZ zuhorit it Wen/y concern:

Be it known that 1, MICHAEL KRAKER, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Lubricating Devices; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device for containing and applying lubricants; and it consists of a transparent containing-cup, a cover adapted to lit and be locked thereon,said cover having a central rod or pin extending inwardly, so as to dip into the lubricant, and a means attached to the cover by which the device may be suspended at any desired or convenient point with relationto the machine for which it is designed.

My invention also comprises details of con struction, which will be more fully explained by reference to the accompanying drawings, in which Figure l is a vertical section through the device. Fig. 2 shows a modification of the oiling-pin.

The usual containing and oiling devices for small machinery-such as sewing-machines, type-writers, and the like-consist of opaque sheet-metal cans of various shapes, having reduced discharge-nozzles, the bodies of said cans being usually so constructed that by a pressure upon some part the interior dimensions will be sutficiently reduced to force a portion of the oil out through the containing vessel and upon the part to be lubricated. These oil-cans are usually made of tin soldered together and are open to three objections: First, when inverted and pressed so as to discharge oil through the nozzle the amount of oil is so much greater than is necessary that the part is flooded and the oil wasted, and this surplus oil must be wiped off, and if not properly attended to the machine soon becomes coated with dirt, which the surplus oil catches; secondly, the can being opaque it is not possible to know when it is empty, and, thirdly, the metal is easily indented and bent if the can is dropped, and joints are thus broken, so as to cause it to leak.

It is the object of my invention to provide a transparent containingyessel through which the quantity of lubricant can always be seen and which is made suffioiently thick and strong, so that it will not be broken by being dropped upon the floor. This vessel may be made ofany suitable or required shape or size and is provided with a screw or other locking cap or closure having a stem or rod extending from its center downwardly into the lubricant in the cup, and this stem is surrounded by a convergent cone, which directs all drip of oil toward the center. Upon the outside of the cap is fixed a loop or eye, by which a device may when the cap is in place be suspended from any convenient nail or hanger. As shown in the accompanying drawings,

A is the containing vessel orcup, made of.

glass or other transparent or translucent material, through which the quantity of oil within may be seen.

B is the cap, which may be made of glass or metal, and is formed with screw-threads or other interlocking lugs by which it may be secured upon the top of the containing vessel. About the cap is asuitable washer 2 for making a joint by closing upon the upper edge of the containing vessel when the cap is in place, and this cap may be made cone-shaped in the center, extending downwardly a short distance into the interior of the vessel A, or a separate cone fitted within it. Through the center of this cone extends a rod or pin 4, which is sufficien tly long so that its lower end will dip into the lubricant within the vessel, and this lower end may be made hollow or pointed, according to the quantity of lubricant which it is desired to take up.

For small machinery I prefer to make a pointed rod, and sufficient lubricant will adhere to it when the cup is disengaged and lifted, so that by touching the point to be lubricated the oil will drop off and perform the service.

If a larger quantity is required than could be carried upon the outside of the rod, the latter may be made hollow and a larger-amount of oil will be taken up by capillary attraction upon both inside and outside of the rod, and when brought into contact with the part to be lubricated the greater portion of this oil will flow off from the rod.

The cone 3 serves to direct any drip which may be deposited within the cap by agitation of the vessel or otherwise and will direct it down the rod and back into the vessel instead of toward the sides, from which it might overflow.

Around the top of the cap is fixed a ring or other attachment, from which projects an arm 5, having a hanging loop 6 at the end, so that the device may be suspended from any suitable pin or hanger within convenient reach of the operator when needed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An improved lubricating device consist ing of a transparent containing vessel, a hollow cap or closure and interengaging means between the closure and neck of the vessel, a cone confined within the hollow cap or closure, and a pin or rod passing through the apex of the cone whereby the inclined walls of the cone direct any drip or surplus oil to the rod and back into the vessel.

2. An improved lubricating device consisting of a vessel having an internally-threaded neck, an externally-threaded hollow cap engaging the neck of the vessel, a cone within the hollow of the cap with its inclined walls converging downwardly from the upper part of the threaded portion of the cap wherebya chamber is formed about the apex of the cone, and a rod or pin passing through the apex of the cone and dipping into the contents of the vessel.

In witness whereof I have hereunto set my hand.

MICHAEL KRAKER.
